A sentence is provided in direct speech. From the four given options, choose the one that most accurately conveys the sentence in its corresponding indirect speech. The scientist said, “We have been working on this project for months.”
- (a)The scientist said they had been working on that project for months.
- (b)The scientist said they have been working on this project for months.
- (c)The scientist said that they were working on that project.
- (d)The scientist said that we had worked on this project.
Answer
Why
Correct — A. The reporting verb said is past, so the quote shifts back.
Tense: present perfect continuous have been working → past perfect continuous had been working.
Pronoun: we, the scientist's team → they.
Demonstrative: this project → that project.
"for months" stays, so the duration survives → option (a).
Why the others are wrong
- (b)The scientist said they have been working on this project for months. — It leaves have been working and this exactly as spoken. After the past verb "said", the standard conversion moves both back: had been working, that.
- (c)The scientist said that they were working on that project. — Were working is the back-shift of "are working", not of "have been working". It also drops "for months", so the report loses how long the work had run.
- (d)The scientist said that we had worked on this project. — Keeping we puts the reporter inside the team. "This" is unchanged, "had worked" loses the continuous sense, and "for months" is dropped.
Concept
After a past reporting verb (said), the tense in the quote moves one step back. Present perfect continuous (have/has been + -ing) becomes past perfect continuous (had been + -ing).
Words tied to the speaker's here and now shift too: this → that, here → there, now → then.
Pronouns follow the people. The scientist said "we", and reported by someone outside that team, it becomes they.
The word "that" after "said" is optional in indirect speech. Option (a) leaves it out and is still correct.
Key facts
- Has/have been + -ing becomes had been + -ing after a past reporting verb.
- In indirect speech, this becomes that and these becomes those.
- A universal truth keeps its present tense even after "said": He said that the sun rises in the east.

Common traps
- Changing the verb but leaving "this": the keyed report changes both.
- Choosing (c) because "were working" looks past: it is the back-shift of "are working", and it drops "for months".
